Profile end face groove feature identification method and system based on heuristic rule

The invention relates to a profile end face groove feature recognition method and system based on a heuristic rule, and the method comprises the steps: S1, constructing a profile part model related to a profile, obtaining an external envelope surface of the profile part model, determining the main direction of the profile part model according to the external envelope surface, and determining the main direction of the profile part model according to the main direction; the section of the profile part model is determined according to the main direction, the contour of the profile part model is determined according to the section, and a blank model is obtained according to the combination of the section and the contour of the profile part model; s2, according to the blank model, an end face with end face groove type characteristics is obtained; and S3, for the end face with the end face groove type characteristics, identifying the groove type characteristics of the end face. The method can effectively recognize
